Data recovery is the process of salvaging data from damaged, corrupted, wrecked or inaccessible primary storage media when it cannot be accessed normally. Often the data is being salvaged from storage media formats such as hard disk drive, storage tapes, CDs, DVDs, RAID, and other electronics.
Although there is some confusion as to the term, data recovery can also be the process of recovering deleted information from a storage media for forensic purposes.
